4MLinux is a miniature Linux distribution focusing on four capabilities: maintenance (by using it as a system rescue live CD), multimedia (for example, for playing video DVDs), miniserver (using the inetd daemon), and mystery (meaning console games).

SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing and chat services. It can be used to send any kind of messages, in addition to normal text messages, including multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, SHA-2, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.

xine is a free multimedia player. It plays back CDs, DVDs, and VCDs. It also decodes multimedia files like AVI, MOV, WMV, and MP3 from local disk drives, and displays multimedia streamed over the Internet. It interprets many of the most common multimedia formats available--and some of the most uncommon formats, too. All those features come in a reusable library (xine-lib) which can easily be embedded in your applications.

cdrtools (formerly cdrecord) creates home-burned CDs/DVDs with a CDR/CDRW/DVD/BluRay recorder. It works as a burn engine for several applications. It supports CD/DVD/BD recorders from many different vendors; all SCSI-3/mmc- and
ATAPI/mmc-compliant drives should also work. Supported features include IDE/ATAPI, parallel port, and SCSI drives; audio CDs, data CDs, and mixed CDs; full multi-session support; CD-RWs, DVD-R/-RW, DVD+R/+RW, BD-R/BD-RE;
and TAO, DAO, RAW, and human-readable error messages. cdrtools includes remote SCSI support and can access local or remote CD/DVD/BD writers.

DerMixD is an audio mixing and network-listening
daemon that is similar to mixplayd but quite
different in its implementation. It supports the
playing of music files on a run-time configurable
number of input channels, mixing them together and
producing output on a run-time configurable number
of output channels. It is controlled over a UNIX domain or TCP socket and supports scripting,
gapless playing of tracks, including filtering of
null samples from padding, use of mpg123's
simple equalizer or a range of effects (mainly via LADSPA), flexible input/output connection, changing playback speed, and more.

WireframeSketcher is a software tool that helps product managers, designers, and developers quickly create wireframes, mockups, and prototypes for desktop, Web, and mobile applications. It’s a standalone application and a plug-in for any Eclipse IDE.

Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.

Gutenprint (formerly Gimp-Print) is a collection of printer drivers for Unix/Linux that currently supports over 1400 printers. It emphasizes quality and flexibility, offering a wide variety of options to meet most printing needs. It includes a CUPS driver, an IJS-based Ghostscript driver, Foomatic data, an enhanced Print plugin for The GIMP, and other printer maintenance utilities. It can be used equally well for fast printing of text or critical printing of high quality graphics and photographs.

JasperReports is a Java reporting library. XML
report templates are used to generate ready to
print documents using data from customizable data
sources, including JDBC. The output can be
delivered to the screen, printer, or stored in
PDF, HTML, XLS, RTF, CSV, and XML format.
